上消化道常规双造影技术的发展极大地提高了我们诊断食管、胃和十二指肠各种炎症性和肿瘤性疾病的能力。尽管越来越多的人接受这种技术，许多放射科医生仍然使用传统的单对比放射摄影作为检查上消化道的主要方式。在最近的一项调查中，超过50%的主要学术机构的放射科医生表示，他们没有在常规基础上进行双对比上消化道检查(1)。在许多情况下，由于缺乏进行或解释这些研究的技术方面的经验或培训，避免使用双重对比技术。单对比与双对比技术的问题最近被胃肠道放射学实践中另一个更不祥的发展所掩盖。资料显示，上消化道透视检查的总次数呈逐渐但稳定的下降趋势。在过去十年中进行了改革（2,3）。这一趋势部分归因于越来越多地使用横断面成像方式，如计算机断层扫描或超声，来评估胃肠道问题。更大的可用性有效的历史
T HE development of routine doublecontrast techniques for examining the upper gastrointestinal (GI) tract has dramatically improved our ability to diagnose a variety of inflammatory and neoplastic diseases in the esophagus, stomach, and duodenum. Despite increasing acceptance of this technique, many radiologists still use conventional single-contrast radiography as the primary modality for examining the upper GI tract. In a recent survey, more than 50% of the responding radiologists at major academic institutions indicated that they did not perform double-contrast upper GI studies on a routine basis (1). In many cases, doublecontrast techniques are avoided because of lack of experience or training in the technical aspects of performing or interpreting these studies. The issue of singleversus doublecontrast technique has recently been overshadowed by another, more ominous development in the practice of GI radiology. Data indicate that there has been a gradual but steady decline in the total number of upper GI fluoroscopic examinations p;rformed during the past decade (2,3). This trend can be attributed partly to the increased use of cross-sectional imaging modalities, such as computed tomography or ultrasound, to evaluate GI problems. The greater availability of effective hista-
